THlLL-CLAMP.

SPECIFICATION forming part of Letters Patent No. 308,149, dated November 18, 1884.

T at whom it may concern.-

Be it known that I, HARBERT K. FoRBIs, a citizen of the United States, residing at O0- lumbus, in the county of Franklin and State of Ohio, have invented a new and useful Clamp,

of which the following is a specification.

My invention relates to improvements in thill-coupling clamps to be used for the placing and removal of anti-rattlers; and the obro jects of my improvements are, first, to provide an implement of more suitable form; sec- 0nd, to afford facilities for adjusting the grip to all sizes of thill-eyes and shackles; and, third, to secure a greater amount of leverage and grip with less physical exertion. I attain these objects by mechanism illustrated in the accompanying drawings, in which v Figure 1 represents a side elevation of the implement in position for operation upon a thill-coupling,,and Fig. 2 a perspective view of the same. Fig. 3 is a side elevation showing the hinged frame of the implement as folded back upon the handle when the same is not in use.

A represents a metal bar having a handle, A, and formed with ahead, A the top of which terminates in a curved point, a, and the bottom is provided with an eye, through which a pintle, 6, passes.

' B is a U-shaped frame, upon the under side of the parallel bars of which recesses or notches b are formed, and at its rear end lugs d are cast. Through an eye therein the pintle 6 passes, and thus secures the frame B to the lever A.

O is the adjustable back piece, being of a half-circle form, the extremities orv ends of which are slotted, as at g, and straddle the horizontal bars of the frame B, as shown in Fig. 2. At the outer ends of the bars a pin 0 or stop, 19, is inserted to prevent the displacement of the part 0 from the frame B, and

across the bifurcated ends of the piece 0 pins h are inserted'in an eye therein, which, when the implement is in use, enter some one of the notches b in the frame B, and thus hold said piece 0 in position.

D represents the axle, (shown in section;) G, the usual anti-rattler; F, the thill-eye upon the end of the thill, (shown broken off,) and E the clip, of ordinary construction and arranged as usual.

The implement is to be used as follows: To uncouple and remove the anti-rattler, raise the thill to a sufficient height and prop the one opposite that which you are first engaged upon. Then hang the half-circle piece 0 over the clip-bar and bring the frame B under the axle and up against the ears of the shackle in the position shown in Fig. 1. Now adjust the half-circle O in the notches b of the frame B to the desired gage, and then bring the lever A up into position, so that the end a thereof will come against the shoulder of the thill-eye, when, by exerting an upward pressure upon the said lever, the thill-eye will be forced back sufficiently to permit of the removal of its bolt, after which the anti-rattler may be removed or replaced, the coupling being made 0 in the same manner as the uncoupling.

I claim In a device for removing anti-rattlers from thill'couplings, the U-shaped frame B, having notchesbalong its under side, adjustable back piece, O,with bifurcated ends adapted to engage with the notched bars, and lever A, pivoted to the frame B and formed with the end a, substantially as described, for the purposes specified.
